Definitions

  • the invention relates to a method and tool for fracturing an underground formation surrounding a borehole for the production of hydrocarbon fluids, such as crude oil and/or natural gas.
  • fracture an underground formation surrounding such a well by pumping a high pressure fluid into an area of the well which is hydraulically isolated from other parts of the well by a pair of isolation packers. The hydraulic pressure exerted to the formation surrounding that area will then initiate fractures in the formation surrounding the well.
  • These fractures may serve to enhance inflow of oil and/or gas into the well, in which case a proppant and/or treatment fluid may be injected into the fractures to further stimulate the oil and/or gas production.
  • the fractures may serve to discharge drill cuttings and/or fluids into the formation.
  • an inflatable sleeve is inflated in the borehole to limit loss of fracturing fluid into the fractures.
  • the use of such a sleeve is known from US parent specifications Nos . 2,798,557, 2,848,052, 4, 968, 10C, 4,657,306, 5, 295, 393 and 3, 062, 29 .
  • US patent specification No. 3,062,294 discloses that the expandable sleeve may be equipped with bit members which are mounted on pistons that are embedded in the sleeve and which are pushed radially into the formation to cleave the surrounding formation.
  • the orientation of the cleaved fractures is essentially dictated by formation stresses so that the fractures are generally not parallel to the borehole.
  • US patent specification No. 5,511,615 discloses a tool for measuring the in-situ borehole stress which tool comprises three short cylinder sections which are arranged in a vertical stack. Each cylinder section comprises two cylinder halves which are pressed against the formation to initiate a fracture generally in a plane that divides the cylinder halves. The cylinder sections are stacked in a vertically offset manner such that the planes that divide the cylinder halves of adjacent sections intersect each other at about 60 degrees. In this manner an accurate determination of the size and orientation of formation stresses can be made.
  • US patent No . ' s 5,678,088 and 5,576,488 disclose other mechanical fracturing tools for measuring formation stresses by temporarily creating fractures in a selected orientation into the formation, which fractures are allowed tc close again after the measurement has been made .
  • US patent No. 2,687,179 discloses a mechanical formation fracturing tool which comprises a pair of semi- tubular expansion members which are pressed in diametrically opposite directions against the borehole wall by hammering a wedge between the expansion members.
  • the known tool is able to obtain at least partial control of the direction of fracturing but has the disadvantage that the impacts generated by the hammering action may damage the borehole wall and crush the surrounding formation in the vicinity of wellbore which reduces the control of the fracturing process.
  • French patent specification 1602480 discloses a fracturing tool where a pair of semi-tubular elements are expanded by hydraulic pressure.
  • the method according to the invention comprises : moving into the borehole a fracturing tool which is adapted to exert a pressure which varies in a circumferential direction against the borehole wall; positioning the fracturing tool at a selected downhole location and circumferential orientation in the borehole; expanding the fracturing tool such that the tool exerts a circumferentially varying pressure against the borehole wall during a selected period of time, thereby initiating in the surrounding formation at least one fracture which intersects the borehole wall at a selected orientation; and - inserting a proppant into at least one fracture during at least part of said period of time.
  • period of time during which the tool exerts a circumferentially varying pressure against the borehole wall is at least 5 seconds.
  • the tool is equipped with a series of formation crushing pins which penetrate into, and are retracted from, the initiated fracture when the tool is example, be carried out while drilling or oil and/or gas production operations take place simultaneously.
  • the tool is equipped with a series of formation crushing pins which penetrate into, and are retracted from, the initiated fracture when the tool is in the expanded position thereof, thereby pushing crushed formation debris into each fracture, which debris forms the proppant which keeps each fracture at least partly open after retraction of the fracturing tool.
  • the use of crushing pins facilitates an easy placement of proppant instantly when the fracture is initiated by the expanded tool without requiring injection of proppant from the surface, which results in a significant reduction of time required for placement of the proppant and elimination of the interruption to other well activities caused by the conventional proppant placement procedures where proppant is injected from the surface.
  • a fracturing tool which comprises at least two substantially longitudinally cut and complementary pipe segments, which are co-axial to a central axis of the tool and which are, when the tool is expanded, pushed radially from the central axis and against the borehole wall by means of a hydraulic, mechanical, or heat activated memory metal actuator mechanism.
  • the fracturing tool may be positioned within an expandable slotted tubular in a well inflow zone within a hydrocarbon fluid bearing formation, which tubular is expanded against the formation as a result of the expansion of the fracturing tool and which tubular is perforated by the formation crushing pins when the pins penetrate into the fractures .
  • a suitable expandable slotted tubular for use in the method is a tubular with staggered longitudinal slots which deform into a prismatic shape as a result of the expansion process.
  • Such an expandable slotted tubular is disclosed in European patent specification No. 0643795.
  • a fracturing tool which comprises two complementary pipe halves, which are each at least 5 long and are radially movable in opposite directions relative to the central axis of the tool and the crushing pins extend through openings between the pipe halves and are expandable in radial directions relative to the central axis of the tool which directions are substantially orthogonal to the directions in which the pipe halves are movable and wherein the fracturing tool is oriented and expanded while the rock crushing pins are actuated to insert crushed formation particles into the opened fracture, and subsequently moved over a length which substantially corresponds to the length of the pipe halves and oriented and expanded while the rock crushing pins are actuated to insert crushed formation particles into the opened fracture, which sequence of steps is repeated until a substantial part of the formation around the well inflow area has been fractured such that elongate fractures are created in the formation over a substantial length of the well inflow zone which fractures intersect the borehole wall at a predetermined orientation.
  • the fracturing method according to the invention is suitable for use as part of a method for enhancing fluid production from an oil and/or gas production well, which method can be carried out at any time of the life cycle of the well and with minimal or no interruption of the oil and/or gas production operations.
  • the fracturing method according to the invention is used to dispose drill cuttings in a formation surrounding an underground borehole which is being drilled towards an oil and/or gas bearing formation.
  • the fracturing tool forms part of a drilling assembly and a drilling fluid comprising drill cuttings is pumped from the drill bit into the fractures surrounding the tool and the tool is equipped with a screen which allows drilling fluid to be pumped back towards the drill bit but which prevents drill cuttings of a size larger than the sieve openings cf the screen to re-enter the borehole.
